arduino-nix

A flake that allows building an arduino-cli environment with certain packages and libraries pre-installed.

Example

You need to provide a package index and library index to use arduino-nix. You can find some at arduino-indexes.

Alternatively, you can download them at https://downloads.arduino.cc/packages/package_index.json and https://downloads.arduino.cc/libraries/library_index.json

From the indexes you create overlays which then make the Arduino packages and libraries available for the wrapArduinoCLI function provided by this flake.
